A. RICHTER. PNEUMATIC CLEANER. APPLICATION FILED DBO. 20. 1905.

s -mmllr b I I W I To all whom it may concem:

Be it known that I, ARMAND Rrcn'rnn, of 76 Bouleyard Michel Brzin,Garches, (Seine & Oise,) Republic of France, chemist, have invented anImproved Pneumatic Cleaner, of which the following is a full, clear, andexact description.

The apparatus which makes the subject-matter of this invention allows ofacting inside the carpets and the liire, so that the cleaning will bevery eflicient.

\ The accompanying drawing shows a way of carrying out this invention.

In this drawing: Figure 1 is a longitudinal vertical section. Fig. 2 isa cross horizontal section made according to line A--A of Fig. 1, andFig. 3 is a cross vertical section made through the apparatus.

As shown in this drawing, the apparatus comprises a distributer ofcompressed air formed of a receiver a to which are secured needle-shapedoutlet pipes b having a beveled point. The receiver a is connected bymeans of a suitable joint 0 and of an india-rubber piped to thecompressed air pipe e.. The receiver a can be lifted and lowered in awell known manner by means of a screw f provided with a hand wheel g inorder to cause the outlet pipes b to enter the material to be cleaned orto withdraw the said pipes from the latter. In these movements, thereceiver is guided by two projections a sliding between'suitable stripsh.

Around the space inclosing the 'distributer is arranged in a well knownmanner, as shown in Fig. -2, an annular sucking chamber i which is to beconnecte H with an exhausting pump by means of a pipe j. The pipe e andwith it the india-rubb er pipe dleading to the distributer are to beconnected with a pump producing compressed air.

In order to be able to regulate according to the requirements the powerof the blast or of the sucking, the pipes e and j are provided withvalves or cocks e, and j.

- To make use of the apparatus for removing dust from clothes, pillows,eider-downs, or carpets, for example; the pipes b are inserted in thearticle by suitably rotating the screw f. The air escaping from thepipes b spreads through the article and removes the dust there- UNITEDSTATES PATENT orrrcn; ARMANl) RICHTER, or GARCHES, FRANCE.

from; the dust is then'sucked in the chamber 13 and carried off by thepipe 9.

It may be useful in some cases not to make use of the blast in acontinuous manner but to sen the com:

pressed air in successive or intermittently into the stuff to becleaned, which results can be obtained by a suitable operation.

Instead of using the screw f to effect the raising'and lowering of thedistributor provided with outlet pipes, any other suitable device couldbe used for imparting the up and down motion to the compressed airoutlet pipes.

Claim:

1. A pneumatic cleaner, comprising a casing, a plurality ofneedle-shaped outlet pipes movabiy mounted in the casing and connectedwith a compressed air pipe, and

means for forcing the outlet pipes into the material to be cleaned.

2. A pneumatic cleaner, comprising a casing, a receiver movably mountedin the casing, said receiver being'provided with a plurality of pointedoutlet pipes and connected with a compressed air pipe, and means forraising and lowering the receiver.

3. A pneumatic cleaner, comprising a casing having guideways on itsinner face, a receiver sliding in said guideways and provided with aplurality of pointed outlet pipes,- a flexible compressed air pipeconnected to the receiver, and means for raising and lowering thereceiver.

4. A pneumatic cleaner, comprising a casing having an exhaust chamber, areceiver ,movably mounted in the easing and provided with a plurality ofpointed outlet pipes,

receiver, a flexible compressed air pipe connected with the receiver,and apipe connected with the exhaust chamber.

The foregoing specification of my apparatus for remov' ing dust frommaterials, carpets, stuffed pieces: of mini ture, and the like, by meansof forced and exhausted air signed by me this fifth day of December,1905.
